I drop my M6 few days ago and now it wont turn on at all.
I can charge and see the battery status but it will not respond to power/play button.
Try email dane-memory and no respond so far.
Anyone know how to fix it?

I guess the strip connecting the touchpad to the main board has become loose. Take it to a GSM repair center, they will be able to fix it.

Don't try to open it up yourself, it's very hard to do it without leaving ugly scratches, and you might end up breaking the strip entirely. I broke my first M6SL like that, its USB connector was having issues, i re-did the soldering on it and next thing you know i turned the MiniPlayer around to put it back together and found that the touchpad strip was now in two pieces... Ouch.

That was last year in spring. I liked the M6SL so much that i bought another one a few months later, and apart from a bit of dust that's somehow gotten on the inside of the case and on the screen, this one is still in perfect shape.

Well, too late.
I cracked open my M6 and it is left fugly scar on the body.
Now it will not even charged.
I bought cowon D2 and thinking about return it and get another M6 SL.
D2 sound quality is not even close to M6, deep bass and high is not there.
What do you think?
